    ABSTRACT:: The relevance of group velocity to the behavior of finite
               difference models of time-dependent partial differential
               equations is surveyed and illustrated. Applications involve
               the propagation of wave packets in one and two dimensions,
               numerical dispersion, the behavior of parasitic waves, and
               the stability analysis of initial boundary-value problems.
